2 Claims.

As the title of the invention implies, we are to be hereinafter concerned with a structural assemblage susceptible of diversified general utility but particularly devoted to road servicing and surface conditioning and ice-breaking work. That is to say, we have been aroused with a desire to provide what may be called a blade and toothed structure of such diversified character as to lend itself admirably well to road work in general. More particularly, we have in mind special structural means which was particularly devised to perform as an ice scraper and remover. That is, a contrivance usable on road clearance vehicles and conveyances, said arrangement being equally well adapted for leveling and smoothing up what is sometimes called a corduroy or washboard gravel road.

To be sure, so-called ice-plows and excavating moldboard type scraper blades are in vogue in road and highway work. Those with which we are familiar, are, in our humble judgment, unsuccessful. Hence, the improvement forming the subject matter of this application for patent. Fundamentally, the invention relies for novelty on a multiple toothed blade assembly, the teeth being sharpened and longitudinally spaced so that the intervening spaces perform to break up and shatter ice films and coatings, thereby permitting removal in a simple and expedient manner.

Further novelty is predicated on a series of standardized interchangeable and reversible teeth with intervening spacing blocks, the blocks having individual bolts and the teeth having individual bolts, these being staggered to prevent loosening of the blocks or teeth whereby to promote longevity, endurance and practical ice cracking and lifting results.

In the drawing:

Figure 1 is an elevational View showing the base or foundation with the improved teeth and spacing blocks arrangement as developed in accordance with our idea.

Figure 2 is an enlarged section on, the line 22 of Figure 1.

Figures 3 and 4. are perspective detail views.

In the drawing, suitable supporting means 5 including hangers serves to accommodate the base or foundation blade and plate 6. This is longitudinally elongated and somewhat arcuate in cross section having bevelled cutting edges 1 and 8. Along the lower efiective or working edge of the blade forming plate 6 we provide the longitudinally spaced cutting teeth 9. These are .55 of block-like construction and have bevelled ends Ill and Illa forming cutting edges. The teeth are bolted in place as at H and these bolts are staggered in relation to the bolts l2 which serve to hold in place the rectangular spacing and assembling blocks 53. By thus staggering the 5 row of bolts H in relation to bolts l2, the blocks prevent turning of the teeth and the teeth in turn prevent turning of the blocks. That is to say, the blocks and teeth coordinate in companion relationship to maintain each other se- 10 curely in place.

By projecting the cutting ends of the teeth beyond the cutting edge 8 of the blade 6 and spacing the blocks l3 upwardly from the cutting edges of the teeth, an assemblage is provided 15 which is secure and dependable. In effect, the teeth dig into the ice, break it up into chunks and thus perform very much in the fashion of hand tools such as are used on pavements and the like for cracking and shattering and remov- 20 ing ice.

We desire to emphasize the reversible foundation plate or blade 6, the reversible and interchangeable teeth, the spacing blocks between the teeth and the oil-set arrangement of fastening 25 bolts between blocks and teeth.

In conclusion, therefore, while we stress the adaptability and importance of the invention as a so-called ice breaking and removing device, it works equally well as a simple excavating device, thus serving to remove corrugations and high spots which always develop in gravel road construction. We have used this structural means to advantage for both removing ice and smoothing up what we term a washboard gravel road. It can be readily understood that a smooth blade would do very little good on a road which is roughened and rendered irregular by the presence of so-called potholes. With this arrangement the teeth will appreciably eradicate the humps and high spots and when the blade is operated at the proper angle with respect to the road bed, it will drag and carry sufiicient loose material along to fill in depressions and holes.

It is thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. Therefore a more lengthy description is thought unnecessary. 50

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

a support, a transversely curved double bevelled blade reversible and constituting a tooth supporting foundation member, spacing blocks along one longitudinal edge and longitudinally spaced apart, cutting teeth intervening between the blocks and projecting beyond the adjacent bevelled longitudinal edge of said blades, and bolts securing the blocks and teeth in place on said foundation blade, the respective sets of bolts for the teeth and blocks being staggered in the man- 10 her and for the purposes described.
